The Dufour glands of workers of Dorylus (Anomma) molestus contain chiefly linear alkenes and alkanes, with (Z)-9-tricosene and tricosane representing over 70%. The glands are relatively small with some indication of very small (nanogram or less) amounts of dihydrofarnesol. Minima, medium, and major workers of Dorylus (Anomma) nigricans contain a similar spectrum of compounds.
